   Mesoscale Discussion 0175
   NWS Storm Prediction Center Norman OK
   1021 AM CDT Sun Mar 14 2021

   Areas affected...Southeast Wyoming and northern Colorado

   Concerning...Blizzard 

   Valid 141521Z - 141915Z

   SUMMARY...Heavy snow and blizzard conditions are expected to
   continue through early afternoon before conditions start to improve
   by mid to late afternoon.

   DISCUSSION...Strong upslope flow continues across much of southeast
   Wyoming and the northern Colorado Front Range. Snowfall rates of 2
   to 3 inches per hour have been observed and will likely continue
   through the remainder of the morning. Winds will slowly back through
   time and become more northerly as the upper-level trough starts to
   shift east over the Plains. This will start to decrease snowfall
   rates across much of the region by mid afternoon. However, until
   that time, heavy snow is expected to persist with the heaviest
   snowfall from areas northwest of Boulder to areas near Cheyenne and
   Laramie.

   In addition to the heavy snow, winds are very strong in the region
   with sustained winds of 25 to 30 knots and gusts 40 to 45 knots
   leading to blizzard conditions in some locations. These winds are
   also forecast to weaken through the afternoon with blizzard
   conditions also likely coming to an end by mid-to-late afternoon.
